USDA hardiness zones: 8b-12. Damaged below 32°F. In zone 8b, in winter, must be in container moved indoors or next to south-facing wall where it will die to ground and revive in spring.
Heat tolerant: Yes.
Drought tolerant: Drought resistant.
Sun: Full sun.
Water once established: Every two weeks after first year. Soil must dry out between waterings. Excess water will reduce flowering.
Soil: Well drained, pH 5.6-6.0 (acidic). Adaptable, but enriched soil beneficial. High nitrogen fertilizer will reduce flowering.
Mulch: Heavily in fall in regions with winter freezes.
Planting: When planting, handle root ball with great care to keep it intact. Roots are very thin and do not hold soil together. After planting, water roots thoroughly, adding a root stimulator. Use flower fertilizer every two months until end of growing season. During the first year in ground, water regularly until winter, then keep almost dry. Bougainvillea can be grown in pots.
Prune: In early spring, remove frost damage. Trim all branches back to 20' for best bloom.
Litter: High. Bract and leaf cleanup, pruning, training.
